IMPROVED STUMP-EXTRAGTOR.

dige rlgrhnls Istant tu im lgrst trthrs aient fmt mating anni at the.. smite TO ALL WHOB IT MAY OONOERN:

Be it known that I, T. J. BOOTH, of Jefferson Line, in the county of Clearfield, and State of Pennsylvania,

have invented a new and useful Improvement in Stump-Extractors and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin the art. to make and use the same, reference being had to the accompanying drawings, forming part of this specification,- in which- Figure 1 is a side elevation of my invention. l

Figure 2 is an end elevation of the same.

Similar letters of reference indicate like parts;

The object of this invention is-to Aprovide a simple and powerful machine for extracting stumps.

It consists of lthe combination andarrangement of the'several principal features, as hereinafter set forth.

The stout trestle-frame, consisting of the base timbers B, uprights A, bracesC, and main beam D, arranged as shown, constitutes the support for the movablevparts, which are chiefly located on topof the said support.

The power-mechanism consists of the combination of a drum, sweep-bar, and tackle, arranged to' operatel in the manner set forth.

E is a sweep-bar, affixed to. the upper end of .the shaft of a drum, I, which has bearings in' the beam D,

and the top piece e'of the frame a e @has shown.

The tackle consists'of the block-J, having two or more sheaves, and a corresponding number of sheaves revolving on the pin u, passing through the cheeks a c, which constitute the shell for the upper slieave and also serve to sustain the top piece e, the said cheeks being aflixedto the beam and thesaid trip piece, as shown.

Onev endof the rope or chain L is attached to some part ofthe machine, as z', and is roveou the upper and lower sheaves, as shown, thus bringing the last part 'of the rope Vor chain up and on a sheave in the sh'ellg, aiiiired to the upper-end of the iron braceh'land thence aixedfhorizontally to the drum I, to which latter the end of the rope or chain is attached, so that, as the sweep-bar E is carried around, the rope orcbain will be wound on the drum, and the stump.(wh'ich in practice, is attachech'by a stump-chain, to the hook K) will be drawn upward by the action of the traction of the tackle.

Thcsweep-bar is bent downward, and is of sui'ciet length to enable theV draught-animal hitched toit to .pass around the machine.

The upper ehdof the sweep-bar is set into a socket ailired to the shaft of the drum, and the said socket i being formed by theiextensionsff from tlre part G and bands g g. AThis socket is of Vcast or wrought iron;

usually the former.

r r is a coupling-clutch, sliding ou the shaft of vthe drum, and held from turning thereon by means of ribs, s s, on the said shaft, which t in 'corresponding slots inthe coupling-clutch.

Projections' from the clutch encounter corresponding projections on the flange-plate Zol the dru'm, as shown.

The clutch is lifted from engagement by a lever, 27:, having a handle, j, conveniently accessibleto the attendant. n Y A This clutch is brought into engagement with the drum by its Weight, and is disengaged therefrom topermit the extracted stump to be lowered to the ground.

The lever vf: is pivoted on the pintle or rod t, projecting from the edge of the upright, d, as shown.A

The forward ends of each base-beam are provided with a roller-attachment, which consists of a cleyis, m, having a. roller, n., and hooksp and o, as shown. When the' machine is to be drawn to another location, the clevises are turned on its pivot-bolt, to bring the rollers under the base-beams. l

This turning under of the said rollers is accomplished by hitching a chainV ou the hooks p, and bitching the team to the chain. The draught-strain will turn the-.rollers under, and hold them in that position.

The hooks o are usedwhen the rollers are to be thrown out from under the base-beams.

z h h h are four auxiliaryviron braces, to 'keep lthe base-beams from spreading.` y

The machine is placed over the-stump to be extracted, so that a vertical sti-ain is brought to bear on it..

The frame is bolted together by vertical and lateral bolts, as'show'n, and is capable of sustaining any vertical strain to which it is likely to be subjected.

Having thus described my invention, I claim as new, 1. The combination, in a stump-extracting machine, of tackle, drum, and sweep-bar, when arranged and operating substantially as shown and described.

2. The coupling-clutch r1', and-its accessory mechanism, when arranged to operate substantially-.as described, in combination with the drum, tackle, sweep-bar, and trestl'c-frame, all as set forth.

3. The clevises m, rollers n, and-hooksp and o, extractor above described, for the purpose set for-th.
